`add-nvidia-repositories` script fails on `ARM64` due to missing `libnvsdm-570`

[Cross reference from SF case `#00416593`] Unfortunately the (Ubuntu-provided) `add-nvidia-repositories` script fails on `ARM64` `570` images as `libnvsdm-570` in not present (yet?) upstream in the Nvidia repos: ``` + apt-get install --assume-yes libnvsdm-570 Reading package lists... Done Building dependency tree... Done Reading state information... Done E: Unable to locate package libnvsdm-570 ``` For now we will skip this test on our side pending a decision from the Google folks on whether we should remove this package install from the script for this `$arch`/`$nvidia_version` combination 🫡 ([Line in the tests here](https://github.com/GoogleCloudPlatform/cloud-image-tests/blob/afaf6c98f272cfabf11a2a351634258273577d12/test_suites/packagevalidation/package_test.go#L84))
